Aug 24, 2008 · All SKS's as well as most common AK's use this system to vent/direct gas to a piston which activates the carrier and then cycles the spent case and chambers a live round. Granted sometimes you have to remove a thing-a ma-bob or two to gain access to the vent hole depending on what type of gun your working on.

Apr 30, 2016 · Hey guys so I was looking at the falks sks-fal hybrid thread. There was mention to the original sks gas port causing the original design to be less then ideally accurate. From my understanding it due to the location of the port causing unequal gas distribution behind the bullet.

Gas system shut off valve and all that?? First thing to check on an M59/66 is the gas valve and port. Assuming it is a standard SKS and not the M59/66, first thing to check is to make sure the recoil spring assembly is in the correct way. Squiggly end goes into the bolt carrier. Second, double check your gas port and clean it out of any carbon ...

Jan 26, 2012 · The idea behind mine, is to block the gas port completely right up at the gas block so that no pressure goes into the gas tube, or thrusts the bolt back against the shoulder inside the gas tube. It's working good. I think if you don't block the gas right at the port, you'll have movement and impact inside the gas tube that ya don't want. jd

Jan 6, 2009 · I noticed a small black line right under the gas port. I believe this to be damage from the factory when they made the hole for the gas port when drilling through the barrel. Is there any way this damage might affect the bore down the road, ie, the chrome in the barrel possibly flaking off while being shot or any other damage?

Jan 4, 2013 · Re: Info Needed - Opening Gas Port « Reply #2 on: January 03, 2013, 04:50:19 PM » Thank you kindly for your response and suggestions, I did check the gas tube and piston over pretty well (they visually look fine, no noticeable pitting or abnormal wear etc) , in addition I thoroughly cleaned both and "run them dry" when firing the rifle.

Oct 14, 2007 · Re: My gas piston is stuck in the gas tube « Reply #14 on: October 21, 2007, 05:08:23 PM » If the tube is corroded too badly, and allows too much blow-by, you may run into functioning problems when reassembled.

Feb 21, 2014 · The gas block is in place but not pinned yet because I wanted to make sure it was on correctly. The gas port is not pinned yet and it isn't even set in place yet because I've had a hard time using a punch and a hammer to drift it in. No gas tube for the gun yet. Will have to order that in the future.

Feb 17, 2015 · Make sure your gas port is free and clear of any carbon build up. Not sure a pipe cleaner with CLP will remove the carbon build up. Get the actual gas port reamer tool or use a drill bit the correct size to clean out by hand. DON'T use a drill. Check for carbon build up inside the gas tube and make sure the piston has full and free travel in it.
